Christmas cards

I decided to make my own cards this year because it sounded like a fun project. I'm just curious if anyone else does this. I'm working up a little trio of penguins sharing a hot beverage (chocolate!) for the front. The plan is to ink one master copy, then use a light box to trace/draw each card front, and add color with Copic markers. It's a pretty simple scene, shouldn't take too much work to draw and color - at least, that's what I'm telling myself!
